Hello,
This morning I tried to turn on my computer but I can't start it!
I looked at the back and I saw a flashing green light (not like usual)
HELP!
I can't start my computer
It's a Compaq Presario, it's 5 years old

Same problem with a HP PC at least 5 or 6 years old, the green light blinks but the PC doesn't turn on. No beeping, the fan doesn't start.
Believe it or not, but the hairdryer technique works perfectly; after 2 minutes of heating the power supply, the light stays green and the PC starts up. Thank you for the advice.

there, it's a little clearer,
what is certain is that your problem comes from one of its components: memory, graphics, or processor,
and the most likely cause is the memory stick; anyway, you would do better to check these components, and I advise you to start with the memory stick, you can move it to the other memory PCI slot, for example.

so your problem comes from the power supply. that's for sure
it seems the only explanation is that the little cables coming out of the box and leading to the motherboard's ATX port are disconnected somewhere. I don't know if this problem is fixable or not, it requires someone a bit more expert to assess that.

It just happened to me: nothing was turning on except for the green diode behind the power supply that was blinking. I thought the power supply was done for. I unplugged the connector from the motherboard that links the power supply to the motherboard and short-circuited the green wire with one of the black wires on the connector, then the power supply fan started up. I plugged the connector back in and the computer started up again! Give it a try.
On my Compaq Presario, the green power supply light and the green light at the front of the tower started blinking after a power outage. I was able to restart my computer by unplugging the power cable from the motherboard; the light stopped blinking, and then after plugging the cable back in, everything was fine.
The current is flowing, plus your fan is running, so it shouldn't be a power issue. Also, you hear beeping, so the problem must come from one of those components above because when the system is triggered, there will be a check of these components, so in case of failure, we hear these beeps.
A big thank you to boogye_157 because his solution works very well.
I have a Compaq Presario and it wouldn't start one day to the next (I took apart the power supply, etc...)
Then nothing, and in fact, you really need to short the wire from the barrette that goes to the motherboard with a black wire (I took the one next to the green one).
And it starts up perfectly.
Don't listen to those who say the power supply is dead (they don't even try to find solutions).
Thanks again, boogye.

Hi, I had the same issue (the PC wouldn't turn on and the green light was flashing) with an HP Pavilion and a Bestec 250W power supply.
I tried the trick given by boogye_157: shorting the green wire on the power supply connector of the motherboard with the black one right next to it, and it worked perfectly, everything restarted.
Thanks again to Boogye_157.

me too, the diode blinks green, nothing else, no beep, it started again after heating the motherboard and the power supply for 5 minutes with a hair dryer!!!
I confirm that the hair dryer technique works perfectly. After 2 minutes of heating, the LED turned back to a steady green and the PC restarted. Thank you for the advice.
The problem is fixed!!
I plugged in the CPU, waited 5 minutes, and then I pressed the power button again, and like a miracle, the CPU is working again!!
THANK YOU ALL FOR YOUR HELP :)

The hairdryer method works!!!!
At first, I tried for a few seconds, then a minute... I saw that nothing was happening so I went back to another desktop computer. Two/three hours later, I came back by chance to test it (thinking logically that it was pointless and that the PC wouldn't turn on) and MIRACLE XD! IT WORKS :D

Dismantle the power supply and change the bulging capacitors on the top or leaking at the base, and everything will be back to normal!
A simple cheap soldering iron is enough; I did it for my TV whose screen took ages to flicker and stabilize, as well as for two TNT receivers that wouldn't turn on at all!
3 faulty capacitors on my TV and 1 on each TNT for €2.10 worth of capacitors!!!

Soldering kits here:

( I specify that I am terrible at electronics; you just need to get started: take photos with your mobile or otherwise before unsoldering a component so you can replace it while respecting the polarity!!! And use capacitors of the same power or higher! For example, you can use 25 volts instead of 10v without worry - industrials sometimes even put less than what is recommended on motherboards!!! )
I also took the opportunity to buy batteries for the CMOS
I made my order from Limousin on Wednesday morning and was delivered by post on Friday morning (a friend told me about this site where he has never had any issues)
http://www.e44.com/alimentations/accus-batteries-piles/piles/piles-boutons/piles-boutons-lithium-3v/piles-20mm/piles-cr2032/
Change the CMOS battery when your battery weakens and the time on the PC is no longer updated upon restarting...
( THANK YOU tanteelise for the tip )

There may also be a resistor to change (with rings of various colors https://www.dcode.fr/code-couleur-resistance to find the right colors; you may need to start from left to right BUT from bottom to top regarding the circles on the faulty resistor : )
In short, it's not too complicated to do;
All about capacitors here:
http://pafgadget.free.fr/bidouillages/condensateurs.htm
YouTube video to change a capacitor (the type is a PRO: carefully follow the advice on electricity residues and respect the polarity of the capacitors; unplug the power supply, of course!!! )

It's the same principle for a PC power supply, a TV that won't turn on or flickers, a TNT receiver that doesn't even go into standby, a motherboard, or any other electronic object with its "cursed" capacitors :)
Similarly, it is advisable to ALWAYS turn off your TV via the RESET/OFF button on the TV so that the capacitors can discharge... rather than leaving the TV on standby indefinitely or unplugging the power when it is in standby!
You can recover capacitors from end-of-life computers, outdated computer screens, TVs thrown away during "bulk waste" days... it will last you a few years... for next to nothing :)
